    Dynamic Regulatory Elements in Single-Cell Multimodal Data Implicate Key Immune Cell States Enriched for Autoimmune Disease Heritability

    To identify noncoding regions with accessible chromatin that associate with cell-state-defining gene expression patterns, researchers leveraged multimodal single-nucleus RNA and assay for transposase-accessible chromatin sequencing data across 28,674 cells from the inflamed synovial tissue of 12 donors.

    Glioma-Derived ANXA1 Suppresses the Immune Response to TLR3 Ligands by Promoting an Anti-Inflammatory Tumor Microenvironment

    The authors tried to enhance the local innate immune response in relapsed high-grade glioma by intracranially injecting poly(I:C) to establish a robust antitumor immune response in this registered clinical trial.

    Abstract

    CPT1A Induction following Epigenetic Perturbation Promotes MAVS Palmitoylation and Activation to Potentiate Antitumor Immunity

    Scientists showed that mitochondrial CPT1A downregulation following viral infection restrained, while its induction by epigenetic perturbations sustained, a double-stranded RNA-activated IFN-I response.

    CAR+ and CAR− T Cells Share a Differentiation Trajectory into an NK-Like Subset after CD19 CAR T Cell Infusion in Patients with B Cell Malignancies

    Investigators conducted a single-cell multi-omics analysis of transcriptional, clonal, and phenotypic profiles from pre- to one-month post-infusion of CAR+ and CAR− T cells from patients from a CARTELL study who received a donor-derived 4-1BB CAR product targeting CD19.

    Harnessing T Cell Exhaustion and Trogocytosis to Isolate Patient-Derived Tumor-Specific TCR

    To study and then harness the tumor-specific T cell dynamics after allogeneic hematopoietic stem cell transplant, scientists typed the frequency, phenotype, and function of lymphocytes directed against tumor-associated antigens in 39 consecutive transplanted patients, for 1 year after transplant.

    The USP7-STAT3-Granzyme-Par-1 Axis Regulates Allergic Inflammation by Promoting Differentiation of IL-5-Producing Th2 Cells

    The authors found that granzyme A- and B-producing Th2 cells played a key role in the promotion of pathogenic Th2 cells via protease-activated receptor (Par)-1 and induced the phosphorylation of p38 mitogen-activated protein kinase.
